This has been circulating around a few other websites and was taken originally from an FZ1 forum.

Considering Nick just recently joined us on CSC, it's fitting we have some of his wisdom to guide us. Thanks for the writeup, Nick. :)



"If you have to stop in a corner, one of two things will happen. One, you will stand the bike up and ride it off the shoulder and into whatever is over there. Or two, you will lay the bike down and slide off the shoulder of the road. Braking is done before, or after a corner. The best thing to do before taking a corner is to grind the thought "I'm going to turn this corner" into your mind."

Hiya FZ1 lovers.
I’ve stewed for two days about the above quote taken from another FZ1OA thread...and finally decided to launch this thread. In past years I would have just rolled my eyes and muttered, “Whatever”…but not anymore. I want to tell you that there are measureable, explainable, repeatable, do-able reasons that make great riders great. And brake usage is at the very tippity-top of these reasons. It’ll save your life, it’ll make you a champion. It will save and grow our sport.
I’ll ask this one favor: Would you open your mind to what I’m about to write, then go out and mess around with it?
To begin: Realize that great motorcycle riding is more subtle in its inputs than most of us imagine. I bet you are moving your hand too quickly with initial throttle and brakes. Moving your right foot too quickly with initial rear brake. The difference between a lap record and a highside is minute, almost-immeasureable differences in throttle and lean angle. The difference between hitting the Camaro in your lane and missing it by a foot is the little things a rider can do with speed control at lean angle. Brakes at lean angle. Brakes in a corner.
Yes, a rider can brake in a corner. Yes. For sure. Guaranteed. I promise. Happens all the time. I do it on every ride, track or street. Yes, a rider can stop in a corner. In fact, any student who rides with the Yamaha Champions Riding School will tell you it’s possible. Complete stop, mid-corner…no drama. Newbies and experts alike.
There are some interesting processes to this sport, mostly revolving around racing. But as I thought about this thread, putting numbers on each thought made more sense because explaining these concepts relies on busting some myths and refining your inputs. Some things must be ingrained…like #1 below.

1)You never, ever, never stab at the brakes. Understand a tire’s grip this way: Front grip is divided between lean angle points and brake points, rear grip is lean angle points and acceleration points, lean angle points and brake points. Realize that the tire will take a great load, but it won’t take a sudden load…and so you practice this smooth loading at every moment in/on every vehicle. If you stab the brakes (um...or throttle...) in your pickup, you berate yourself because you know that the stab, at lean angle on your motorcycle (and bicycle, btw), will be a crash.

2)Let’s examine tire grip. If you’re leaned over at 95% (95 points in my book Sport Riding Techniques and fastersafer.com) of the tires’ available grip, you still have 5% of that grip available for braking (or accelerating). But maybe you only have 3%!!! You find out because you always add braking “points” in a smooth, linear manner. As the front tire reaches its limit, it will squirm and warn you…if that limit is reached in a linear manner.
It’s the grabbing of 30 points that hurts anyone leaned over more than 70 points. If you ride slowly with no lean angle, you will begin to believe that aggressiveness and grabbing the front brake lever is okay…and it is…until you carry more lean angle (or it’s raining, or you’re on a dirt road or your tire’s cold…pick your excuse). Do you have a new rider in your life? Get them thinking of never, ever, never grabbing the brakes. Throttle too…

3)If you STAB the front brake at lean angle, one of two things will happen. If the grip is good, the fork will collapse and the bike will stand up and run wide. If the grip is not-so-good, the front tire will lock and slide. The italicized advice at the beginning was written by a rider who aggressively goes after the front brake lever. His bike always stands up or lowsides. He’s inputting brake force too aggressively, too quickly...he isn't smoothly loading the fork springs or loading the tire. He may not believe this, but the tire will handle the load he wants, but the load must be fed-in more smoothly…and his experience leads to written advice that will hurt/kill other riders. “Never touch the brakes at lean angle?” Wrong. “Never grab the brakes at lean angle?” Right!
But what about the racers on TV who lose the front in the braking zone? Pay attention to when they lose grip. If it’s immediately, it’s because they stabbed the brake at lean angle. If it’s late in the braking zone, it’s because they finally exceeded 100 points of grip deep in the braking zone…if you’re adding lean angle, you’ve got to be “trailing off” the brakes as the tire nears its limit.

4) Radius equals MPH. Realize that speed affects the bike’s radius at a given lean angle. If the corner is tighter than expected, continue to bring your speed down. What’s the best way to bring your speed down? Roll off the throttle and hope you slow down? Or roll off the throttle and squeeze on a little brake? Please don’t answer off the top of your head…answer after you’ve experimented in the real world.
Do this: Ride in a circle in a parking lot at a given lean angle. That’s your radius. Run a circle or two and then slowly sneak on more throttle at the same lean angle and watch what your radius does. Now ride in the circle again, and roll off the throttle…at the same lean angle. You are learning Radius equals MPH. You are learning what throttle and off-throttle does to your radius through steering geometry changes and speed changes. You are learning something on your own, rather than asking for advice on subjects that affect your health and life. (You will also learn why I get so upset when new riders are told to push on the inside bar and pick up the throttle if they get in the corner too fast. Exactly the opposite of what the best riders do. But don’t believe me…try it.)
Let me rant for a moment: Almost every bit of riding advice works when the pace is low and the grip is high. It’s when the corner tightens or the sleet falls or the lap record is within reach…then everything counts.
“Get all your braking done before the turn,” is good riding advice. But what if you don’t? What if the corner goes the other way and is tighter and there’s gravel? It’s then that you don’t need advice, you need riding technique. Theory goes out the window and if you don’t perform the exact action, you will be lying in the dirt, or worse. Know that these techniques are not only understandable, but do-able by you. Yes you! I’m motivated to motivate you due to what I’ve seen working at Freddie’s school and now the Champ school…
I’m telling you this: If you can smoothly, gently pick-up your front brake lever and load the tire, you can brake at any lean angle on an FZ1. Why? Because our footpegs drag before our tires lose grip when things are warm and dry. It might be only 3 points, but missing the bus bumper by a foot is still missing the bumper! If it’s raining, you simply take these same actions and reduce them…you can still mix lean angle and brake pressure, but with considerably less of each. Rainy and cold? Lower still, but still combine-able.

5)So you’re into a right-hand corner and you must stop your bike for whatever reason. You close the throttle and sneak on the brakes lightly, balancing lean angle points against brake points. As you slow down, your radius continues to tighten. You don’t want to run off the inside of the corner, so you take away lean angle. What can you do with the brakes when you take away lean angle? Yes! Squeeze more. Stay with it and you will stop your bike mid-corner completely upright. No drama. But don’t just believe me…go prove it to yourself.

6)Let’s examine the final sentence in the italicized quote. The best thing to do before taking a corner is to grind the thought "I'm going to turn this corner" into your mind.
No, that’s not the best thing. It’s not the worst thing and I’m all for positive thinking, but we all need to see the difference between riding advice and riding techniques. This advice works until you enter a corner truly beyond your mental, physical or mechanical limits. I would change this to: The best thing to do before taking a corner is to scan with your eyes, use your brakes until you’re happy with your speed and direction, sneak open your throttle to maintain your chosen speed and radius, don’t accelerate until you can see your exit and can take away lean angle.
7)Do you think I’m being over-dramatic by claiming this will save our sport? Are we crashing because we’re going too slowly in the corners or too fast? Yes, too fast. What component reduces speed? Brakes. What component calms your brain? Brakes. What component, when massaged skillfully, helps the bike turn? Brakes. If riders are being told that they can’t use the brakes at lean angle, you begin to see the reason for my drama level. When I have a new rider in my life, my third priority is to have them, “Turn into the corner with the brake-light on.”

I’ve said it before: This is the only bike forum I’m a member of. I like it, I like the peeps, I like the info, I love the bike. Could we begin to change the information we pass along regarding brakes and lean angle? Could we control our sport by actually controlling our motorcycles? If we don’t control our sport, someone else will try. Closed throttle, no brakes is “out of the controls”. Get out there and master the brakes.
Thanks, I feel better.

Nick knows his stuff and he's able to communicate that knowledge.

I went to the Freddie Spencer school (back when there was one) three times and learned a lot from him.

DID he?

I'll look for him. We actually met once late at night at a WERA 24hrs West in the pits at Willow Springs, in the early/mid '80's. He was with Mitch Boehm and some others from the magazines if I remember correctly. I'd like to see if he remembers that.+

If you're out there Nick, shoot me a PM please.

That really is a great read. It's something that I have always been unsure about and it cleared a lot of things up for me. It is pretty much what Cornfed spoke about in his new rider class.

Wife is scheduled in the Abate class this weekend.

I know they tought the same principle when I went through but not in depth until the advanced class.

Agreed with cornfed's new rider class. And this was a great read! I really need to work on this!

Cycle Monkey, I definetely remember the Willow 24 hours...were you there the year Wes Cooley went quicker in the dark than anyone went in the light? Amazing stuff.

Drano...thank you for posting my rant on braking...man, I was so chapped at the quote I pasted in at the top. I had been reading a thread on that forum and finally couldn't stand it anymore!! (But I love the FZ1OA forum.) I know it's a long post, but I really hope new riders take the time to study it.

Am I nieve to believe that brake usage at lean angle can save our sport? Some new-rider class graduates leave class with the belief that they can't touch the brakes at lean angle...fairly do-able in a parking lot at 25 mph...gets a bit tougher on the RSV4 you buy the day after graduating, entering a downhill decreasing radius corner at twice the speed limit. Every new-rider instructor is doing God's work, but I always encourage them to "teach beyond the written curriculum" and make sure their graduates know that trailbraking and brakes at lean angle are skills they need. Nobody's asking me, but I'd change the new-rider courses to include trailbraking.

In fact, it would be third on the priority list, it's that big of a deal. First would be eye usage...then focus/concentration...then trailbraking.

Dang, I'm ranting again...pretty worked up about it. Tough killing our own members with incomplete advice. NI

Sometimes I find it difficult to keep telling my students, that take the Beginner Rider Course, that they must do all their braking before leaning the bike over in a turn knowing that this is just partial information. Unfortunately, this is mandated by MSF when teaching the BRC. I usually have at least one student ask me in every single class, "What is trailbreaking?" I am happy to explain it to them while on a break but then let them know that they should not try to apply it during the class. The fourth skill evaluation in the BRC would actually deduct points for this.

The great thing about the ARC-ST, Advanced Rider Course-Sportbike Technique, is it encourages braking while leaned over in a turn and there are a number of range exercises to practice this. Not to mention most of the curriculum was adapted from a certain someone's book. :)

What about bikes with ABS brakes? Does Nick's advice to never stab the brakes still apply to ABS-equipped machines? Curious ...

Uglydog...it's fantastic that you work "off the books" with your answers about trailbraking. I have a friend who teaches the BRC in California...after graduation when all is said and done, he walks his class onto the course and discusses and demonstrates trailbraking...let's them know that you can type a letter with your index fingers but you may want to think about touch-typing as the next step. Good for you...you know my opinion.

Psyclone...pay attention to when you get "into" ABS...if it cycles right away you are inputting brake pressure way too suddenly, not allowing the fork springs and tire to load and the contact patch to grow with a smoother squeeze. If it cycles late in the brake zone, you have simply built brake pressure to the point the tire is locking, using ABS as intended.

The problem with ABS cycling with initial brake pressure is simply that every cycle adds a bit of distance to the stop...but not much these days. For me, the real problem is you begin to think aggression with a motorcycle's controls is okay...one day after lunch your friend asks, "Ya wanna ride my ($25,000) RC30 down the canyon?" Grab. Crunch. Either no more friendship or a big check being written.

My opinion: ABS should be used as a safety net, a warning that you have finally exceeded a tire's grip under braking.

I love how critically this site regards riding...high stakes bring high rewards. There's nothing I know of in the world as good as motorcycle riding.

Woo hoo! I'm doing it right!

When I took the MSF Basic Rider course, I had an old Harley Sportster, and it handled a lot differently than my current bike. The main thing I remember my instructor saying about braking was to never lay down your bike. As long as you still have wheels under you, you still have braking ability, and some measure of steering control. If someone turns left in front of you and there is not enough time/distance to swerve out of danger - get on the brakes, but don't lock them up. Stay on the brakes and ride all the way into the other vehicle. You may be able to slow down enough so you don't get hurt.

I have two friends who laid down their bikes when they got cut off. One of them ended up with a broken femur. The other ended up with a prosthetic leg.
